Unraveling Neurodevelopmental Disorders: Signalling Pathways as Potential Targets for Therapeutic Intervention in Autism Spectrum Disorder

Introduction: Autism Spectrum Disorder (ASD) presents a multifaceted challenge with limited therapeutic options and a need for early biomarkers. Understanding disrupted signalling pathways offers promise for intervention and assessment. Methods: Literature review spanning genetic, pre-clinical, and patient studies elucidating pathways implicated in ASD pathogenesis, including melatonin, mTOR, Retinoic acid, Hedgehog, Notch and Wnt signalling. Results: Core components of key signalling pathways, such as melatonin, mTOR, Retinoic acid, Hedgehog, Notch and Wnt, are dysregulated in ASD. These pathways regulate crucial aspects of the nervous system, including immune function, neuronal growth, neurotransmission, and metabolism. Discussion: Manipulating these pathways could potentially modify ASD traits by influencing brain development and immune homeostasis. Targeting specific nodes within these pathways may offer novel therapeutic approaches for ASD management. Additionally, identifying biomarkers associated with pathway dysregulation could enable earlier diagnosis and monitoring of disease progression. Conclusion: Understanding the intricate interplay of signalling pathways in ASD pathogenesis provides insights into potential therapeutic targets and biomarkers. Further research into the manipulation of these pathways and their impact on ASD traits is warranted to advance personalized treatment strategies and improve outcomes for individuals with ASD.
